For searchability, have you tried using the actual search feature? If you haven't noticed it, it's the looking-glass icon on the upper right. It's powered by Google, and it will find words in the body of the text. What's missing is search results being sorted by newest first. And the most recent posts aren't indexed by Google yet.
Since you brought it up, I took a quick look at your 'high-quality content'. Sorry Aisha, it's OK, but nothing special. Nice pictures, some superficial opinions that might be considered original to a Western audience. Nothing that millions of other people couldn't create.
You're not going to get discovered without promoting yourself. I'm glad regular people are posting here, not just artists and intellectuals. It's good for the general atmosphere of the site. You could be popular if you promoted a charity or organized a local Steemit meetup, for example. Just don't expect to be richly rewarded for posting pictures of bikes or henna tattoos. Please take advantage of @yallapapi's advice in his comment here and in his posts.
And by promoting yourself I don't mean upvoting your own comment. That's considered a faux pas here, unlike upvoting your own post. You might disagree, but that's a convention which grew naturally. I'd consider upvoting your own comments worse than paying for vote bots.
